EM Simulation of 28 GHz Series-Fed Patch Antenna Array for 5G

EM Simulation of 28 GHz Series-Fed Patch Antenna Array for 5G

Series-fed patch elements forming an array are simulated to demonstrate antenna performance and beamforming including S-parameters, gain, and effective isotropic radiated power (EIRP) at 28 GHz.   Beam steering is performed in one plane by adjusting the phasing at the input ports to each of eight elements.

mmWave Channel Modeling with Diffuse Scattering in an Office Environment

The millimeter wave frequencies being planned for 5G systems pose challenges for channel modeling. At these frequencies, surface roughness impacts wave propagation, causing scatter in non-specular directions that can have a large effect on received signal strength and polarization. To accurately predict channel characteristics for millimeter wave frequencies, propagation modeling must account for diffuse scattering effects. Wireless InSite’s diffuse scattering capability is based on Degli-Esposti’s work.
